Abstract: In this thesis the laserlight-propagation in a Laser-Fusionreactor at various densities and density-profiles shall be examined in order to determine the optimum density under various conditions. For this purpose the computer code RAMSES has been written, which simulates in twc dimensions the photon-motion through a gas or plasma. The method of simulation is essentially a PIC- (particle-in-cell) model. The programme takes into account refraction-effects and variations of the group velocity caused by the local electron density, which may be supplied either explicitly or calculated from the ionisation rates. A parameter study has been carried out in oder to calculate the laser-transmission-rates for different density profiles and under various conditions. With the restraining condition of a transmission of 95 % of the original pulse energy into the target region the optimum density in Bach case is determined. Finally as an example for application - these optimum densities lead to restrictions an the wall-temperature of the reactor-vessel.
